hello Hemant..thanks for the query. May i know what is your age & since how many days are you facing these problems? In addition how is your mood, energy levels? Is there any significant change in your sleeping & eating patterns & whether there are symptoms like increased irritation, sudden startle upon loud noise or excessive anxiety over trivial things? what symptoms you are describing are suggestive of attention & concentration difficulties plus anxiety symptoms. These can occur in various anxiety disorders as well as in depressive disorders. Hence you should consult a Psychiatrist for detailed evaluation. you will be offered various treatments like Medications (ssri type drugs) counseling techniques (behavior modification, cognitive behavior therapy etc.) don t worry..good luck
